Thanks for help and suggestions. Seem like the main problem is that I
got the the wrong order on the layers when calling ogcserver. Which
means an area layer is covering the other layers. Still not sure why
that happens. Might be QGIS making the error(or most likely me). Seems
like it is OK as long as I request only one layer.
I addition to that I have created some error in the in the bounding
box in my request.
